Thaum cov engineers xav tau micro hlau txhaj molding Hoobkas muaj peev xwm rau qhov chaw qis dua 5 hli nrog ± 0.01 hli kam rau ua, lawv tsis tshua pib nrog Google tshawb. Lawv pib nrog cov qauv ua tsis tiav - cobalt alloy nozzle uas tawg thaum lub sij hawm ntsuas hydraulic, lub twj tso kua mis vaj tse bore uas ntws tawm ntawm ib puag ncig tom qab kev kho cua sov, los yog lub winch center ncej cov menyuam uas hnav tsis sib xws tom qab 200 teev nyob rau hauv ntsev-laden offshore tej yam kev mob. Peb tau pom tag nrho peb - thiab txhim kho txhua tus tsis yog los ntawm kev kho qhov kam rau ua, tab sis los ntawm kev rov xav dua yuav ua li cas cov khoom siv me me txuas rau qhov sib txawv ntawm cov hmoov hlau metallurgy thiab kev ntseeg tau ua haujlwm.
Micro hlau txhaj tshuaj molding tsis yog tsuas yog "me me MIM" - nws xav tau metallurgical tswj ntawm micron nplai
Muaj tseeb micro hlau txhaj tshuaj molding (μMIM) txawv ntawm tus qauv MIM nyob rau hauv peb txoj kev tsis sib tham: hmoov particle loj faib yuav tsum nyob qis dua 5 μm D90, kev tshem tawm binder yuav tsum tau gradient thermal profileing los tiv thaiv micro-cracking hauv cov phab ntsa nyias (<0.3 hli), thiab sintering yuav tsum ua kom tiav ≥98.5% theoretical ntom yam tsis muaj nplej coarsening. Ntau tus neeg muag khoom sau npe "micro" yog tias lawv qis dua 10 g - tab sis qhov tiag μMIM qhov hnyav 0.05-2.5 g thiab cov yam ntxwv zoo li 0.15 mm-inch cua txias channel, 0.08 mm phab ntsa thicknesses, thiab GD&T callouts rau qhov tseeb hauv 0.005 mm.
Tias yog vim li cas xaiv cov khoom siv tsis yog xaiv tau - nws yog thawj qhov kev txiav txim siab engineering. AMS 5387 cobalt alloy ua haujlwm qhov twg 316 stainless tsis ua haujlwm: nyob rau hauv high-ceev slurry ib puag ncig, ntawm 450 ° C kev khiav hauj lwm temps, nyob rau hauv cyclic qaug zog loads tshaj 10⁷ cycles. Tab sis nws cov qauv nplua-grained ua rau nws tsis zam txim thaum lub sij hawm debinding. Peb siv ob-theem hnyav / cov txheej txheem thermal nrog lub sijhawm saib xyuas huab hwm coj-tsis tas sijhawm - vim tias batch-rau-batch variation nyob rau hauv binder diffusion tus nqi ncaj qha cuam tshuam rau ntsuab ib feem.
Vertical integration daws qhov outsourcing so
Feem ntau μMIM tsis ua haujlwm taug qab rov qab mus rau kev sib tw: MIM tus neeg xa khoom nkoj sintered blanks; lub khw machining tawm tsam nrog kev ua haujlwm ntawm 3-mm-inch flanges; Lub tshuab kho cua sov tsis tuaj yeem rov ua dua qhov tseeb austenitizing ramp xav tau rau AMS 5387's carbide dispersion. Peb khiav tag nrho peb kauj ruam hauv qab ib lub ru tsev ISO 9001-certified hauv Qingdao - thiab qhov ntawd hloov txhua yam.
- CNC machining siv 5-axis mills nrog cov cuab yeej nyob thiab hauv kev soj ntsuam - qhov tseem ceeb thaum ntsib 0.2 hli-thick flange nrog ± 0.003 hli flatness
- Kev kho cua sov suav nrog lub tshuab nqus tsev carburizing rau T800-based Cheebtsam, nrog rau cov pa oxygen ib nrab siab tswj rau <10⁻⁴ mbar los tiv thaiv qhov chaw oxidation ntawm complex contours
- Nto xov siv electropolishing nrog qhov ceev tam sim no mapped rau hauv zos geometry - tsis muaj qhov muag tsis pom kev, tsis muaj micro-pits hauv txoj kev ntws.
Peb tsis yog tuav kev zam xwb. Peb tuav * ua haujlwm * kam rau ua: nto roughness Ra ≤ 0.2 μm ntawm lub ntsej muag sealing, micro-hardness sib xws hla 0.5 hli hla ntu, thiab cov seem kev ntxhov siab tau txheeb xyuas ntawm XRD diffraction - tsis yog hardness Rockwell C checks xwb.
Design-for-manufacturing pib ua ntej thawj CAD cov ntaub ntawv tau txais kev cawmdim
Cov neeg siv khoom feem ntau nug: "Koj puas tuaj yeem ua qhov no?" Peb teb: "Yog - tab sis tsuas yog yog tias peb kho lub vojvoog ntawm no, txav lub rooj vag qhov chaw nyob ntawd, thiab qhia qhov sib txawv sintering cua." Piv txwv li, ib tug cobalt alloy plug nrog ib tug 0.4 hli internal xov ua tsis tau tejyam rov qab mus txog rau thaum peb hloov los ntawm internal threading post-sinter rau xov-forming thaum lub sij hawm ntsuab-xeev machining - ces siv tsawg-kub nitriding es tsis txhob ntawm cov pa hardening. Qhov kev hloov ntawd txiav cov seem ntawm 37% mus rau 1.8%.
Peb validate txhua daim duab rau μMIM feasibility - kuaj cov kaum sab xis (tsawg kawg 0.5 °), tsis txhob ntse sab hauv cov ces kaum (R ≥ 0.1 hli), xyuas cov phab ntsa thickness hloov (tsis muaj> 3: 1 piv), thiab qauv binder flow los kwv yees cov kab hauv cov phab ntsa nyias nyias. Yog tias koj GD&T hu tawm txoj haujlwm sib xyaw ntawm peb lub datums sib nrug 2 hli sib nrug, peb yuav chij nws - thiab tawm tswv yim ib qhov chaw datum uas muab cov txiaj ntsig zoo ib yam nrog 40% qis nqi tshuaj xyuas.
Kev ntseeg tsis tau ntsuas hauv cov ntawv pov thawj - nws tau tsim rau hauv txhua qhov ntau
Traceability tsis yog cov ntaub ntawv. Nws yog laser-etched ntau codes ntawm txhua qhov chaw, raw cov ntaub ntawv pov thawj khi rau ib tug neeg sintering khiav, thiab CMM cov ntaub ntawv archived rau 15 xyoo - tsis yog rau kev soj ntsuam, tab sis yog li thaum ib tug neeg qhia txog hnav ntawm 12,000 teev ua hauj lwm, peb muaj peev xwm rub lub pes tsawg tshav kub-kho log, binder batch ntaub ntawv, thiab optical ntau lawm interferometry.
Peb lub tuam txhab micro hlau txhaj tshuaj molding ua haujlwm hydraulic OEMs hauv lub teb chaws Yelemees uas xav tau EN 10204 3.1 ntawv pov thawj, cov neeg ua haujlwm oilfield hauv Texas xav tau API Q1 ua raws, thiab cov tsim twj tso kua mis hauv Singapore xav tau ASME BPE nto tiav validation. Dab tsi koom ua ke lawv tsis yog thaj chaw - nws yog qhov tsis kam lees txais "zoo txaus" ntawm qhov chaw uas foob, ntsuas, lossis tig nyob rau hauv lub neej tseem ceeb.
Yog tias koj qhov project me me tom ntej no suav nrog cobalt alloys, cov phab ntsa nruj-hloov nyias, lossis cov chaw ua haujlwm uas yuav tsum muaj sia nyob cov xov xwm abrasive - pib nrog tus cwj pwm ntawm cov khoom, tsis yog tshuab specs. Pib nrog cov txheej txheem ua tswv, tsis hais nrawm. Pib nrog tus khub uas kho txhua qhov sib txawv ntawm 0.02 hli raws li kev tshawb nrhiav hauv paus, tsis yog kev zam zam. Qhov no yog li cas precision yuav kwv yees tau.
